		# Testing and monitor the cpu desire performance, frequency, load,
		# power consumption and throughput etc. when this script trigger
		# gitsource test.
		# 1) Download and tar gitsource codes.
		# 2) Run gitsource benchmark on specific governors, ondemand or schedutil.
		# 3) Run tbench benchmark comparative test on acpi-cpufreq kernel driver.
		# 4) Get desire performance, frequency, load by perf.
		# 5) Get power consumption and throughput by amd_pstate_trace.py.
		# 6) Get run time by /usr/bin/time.
		# 7) Analyse test results and save it in file selftest.gitsource.csv.
		#8) Plot png images about time, energy and performance per watt for each test.
